Features
High reliability by all required functions integrating
1. Continuous conduction mode suitable for the system with a large amount and frequency of a current change.
2. ON/OFF support of the main converter and the load by a PG signal and a hold function.
3. Hold function against an AC temporary blackout
4. Over-voltage protection with a feedback loop absence detecting function
5. Quick soft-start
6. Improvement of the load regulation by a Gm amplifier
Small and high reliability system
Example of Application Circuit
• The HA16174 stabilizes the over-current control of PFC unit and sets the S/S ineffective time by a hold function in time of an AC temporary blackout.
• The HA16163 makes up a full bridge and achieves small and high efficiency trances.
